The three main devices (symbols) in the Archdeacon blazon are the chevron, martlet and tower. The three main tinctures (colors) are or, sable and argent .
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.1. Along with, argent, or silver it forms the two “metals” of heraldry – one of the guidelines of heraldic design is that silver objects should not be placed upon gold fields and vice versa 2. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.3.
Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 4. In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 5. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 6.
Argent is the heraldic metal Silver and is usually shown as very pure white. It is also known more poetically as pearl, moon (or luna) 7. In a sketch or drawing it is represented by plain, unmarked paper 8.
The chevron is one the major shapes used upon a shield, known as ordinaries. The inverted ‘V’ of the chevron is perhaps thought to have originated to represent a military scarf folded on the shield 9, or additional cross-pieces used to strengthen the shield and painted a different colour.10. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 11, possibly becuase of its resemblance to the roof truss of a house.
The martlett is by far the most common bird to appear in British Heraldry, perhaps only equalled by the eagle, however it is not a species ever to be found in an ornithologists handbook! The word itself is though to have come from the French word merlette, the female blackbird and itself a similar type of charge used in French Heraldry. 12. Over time the image has become quite stylised, without visible legs or distinctive feathers. Wade suggests that this representation arises from “the appearance of the bird of paradise to ancient travellers” 13. Other bird species may be named in coats of arms (cornish chough is a frequent example) but in actual execution their appearance is often indistinguishable from the martlet.
Architectural items, from individual components to entire buildings 14 feature frequently as charges In a coat of arms. Not surprisingly, considering the times from which many arms date, fortifications are common. The tower Is a typical example of an object from the world of architecture adopted, albeit in a stylised form, for use in heraldry. It can be placed alone, or frequently with three turrets on the top, known as a tower triple towered, and can have doors and windows of a different colour. 15 In continental European heraldry they are often accompanied by pictorial effects such as armoured knights scaling them on ladders.
